Five Factors Relating to Students\u27 Academic Advising Experience at a Small, Private, Liberal Arts University

Academic advising is an important part of the college experience but has innate challenges. Much research has been done to try to improve the quality of students’ academic advising experiences, but limited research has focused on student factors that contribute to their experiences. This project sought to discover if certain factors impacted students’ academic advising experiences for better or worse at one institution. The research question guiding the study was “Is there a relationship between students’ academic preparedness, school, gender, class, and ethnicity with their academic advising experiences at a small, private, liberal arts university?” The 2012 NSSE 2.0 Pilot Study, Academic Advising Module served as the dependent variable and Independent Samples T-tests and Analyses of Variances were calculated for the five aforementioned factors. Statistical results indicated that four factors did not strongly correlate to students’ academic advising experiences, positively or negatively. However, students’ ethnicity (White vs. Non-White) did produce a strong statistical correlation between the means (p = .002). A main reason for this may be the number of international students who were part of the sample and the multiple ways in which they were supported at the institution in the study. While contributing to academic advising literature, the study also draws attention to the high value of multiple touch-points on students’ academic advising experiences. The more faculty and staff take time to invest in students’ academic success, the greater those students’ estimation and satisfaction with their advising

Through the Fire: Using Derailment Research to Lead Change in the COVID-19 Era

The current coronavirus pandemic has created an undeniable crisis in the United States and in virtually all parts of the world. Leaders in all sectors need effective modes of thinking to lead change in this COVID-19 era. In this article, we utilize the concept of derailment to offer perspectives for such leaders. Using relevant interview data from a recent in-depth study (Strietzel, 2020a), we apply the stories and lessons from 25 “derailed” leaders to provide a three-layered approach to leading change while navigating the current crisis. Implications and recommendations for leaders are discussed

Applying Derailment Advice: How Educational Leaders Can Use Job Loss Lessons to Navigate the COVID-19 Crisis

The COVID-19 pandemic has upended life and work for people around the globe. This upheaval has created new challenges for those serving in or studying at higher education. College administrators have been forced to adapt, and many have used wisdom gained from past crises as proxies for the current crisis. After many months in a pandemic, however, many leaders are still searching for effective frameworks and mental models to guide their efforts. In this article, we offer the concept of derailment as a proxy for leaders in challenging times. We examined interview data from a recent in-depth study of 25 derailed leaders (Strietzel, 2020) and explored similarities between experiencing derailment and leading through a pandemic. Using the lessons learned from derailed administrators, we provide a three-layered approach to navigate the current crisis. Findings and implications encourage higher education leaders to focus on their purpose, growth, and environment

On moments of downward passage times for spectrally negative L\'evy processes

The existence of moments of first downward passage times of a spectrally negative L\'evy process is governed by the general dynamics of the L\'evy process, i.e. whether the L\'evy process is drifting to $+\infty$, $-\infty$ or oscillates. Whenever the L\'evy process drifts to $+\infty$, we prove that the $\kappa$-th moment of the first passage time (conditioned to be finite) exists if and only if the $(\kappa+1)$-th moment of the L\'evy jump measure exists. This generalises a result shown earlier by Delbaen for Cram\'er-Lundberg risk processes \cite{Delbaen1990}. Whenever the L\'evy process drifts to $-\infty$, we prove that all moments of the first passage time exist, while for an oscillating L\'evy process we derive conditions for non-existence of the moments and in particular we show that no integer moments exist.Comment: 15 page

Emulating the early phases of human tooth development in vitro

Functional in vitro models emulating the physiological processes of human organ formation are invaluable for future research and the development of regenerative therapies. Here, a developmentally inspired approach is pursued to reproduce fundamental steps of human tooth organogenesis in vitro using human dental pulp cells. Similar to the in vivo situation of tooth initiating mesenchymal condensation, a 3D self-organizing culture was pursued resulting in an organoid of the size of a human tooth germ with odontogenic marker expression. Furthermore, the model is capable of epithelial invagination into the condensed mesenchyme, mimicking the reciprocal tissue interactions of human tooth development. Comprehensive transcriptome analysis revealed activation of well-studied as well as rather less investigated signaling pathways implicated in human tooth organogenesis, such as the Notch signaling. Early condensation in vitro revealed a shift to the TGFß signal transduction pathway and a decreased RhoA small GTPase activity, connected to the remodeling of the cytoskeleton and actin-mediated mechanotransduction. Therefore, this in vitro model of tooth development provides a valuable model to study basic human developmental mechanisms.DFG, 414044773, Open Access Publizieren 2019 - 2020 / Technische Universität Berli

Implants in patients with oral manifestations of autoimmune or muco-cutaneous diseases : a systematic review

To give an overview on implant survival rates in patients with oral manifestations of systemic autoimmune (oral Lichen planus (oLp), Pemphigus (Pe)), muco-cutaneous (Epidermolysis bullosa (EB)), autoimmune multisystemic rheumatic diseases (Sjögren´s syndrome (SjS), systemic Lupus erythematosus (sLE), or systemic Sclerosis (sSc)). Systematic literature review (PubMed/Medline, Embase) using MESH and search term combinations, published between 1980 and August 2018 in English language reporting on dental implant-prosthetic rehabilitation of patients with oLp, Pe, EB, SjS, sLE, sSc, study design, age, gender, follow-up period (? 12 months), implant survival rate. Implant-related weighed mean values of implant survival rate (wmSR) were calculated. After a mean follow-up period (mfp) of 44.6 months, a wmSR of 98.3 % was calculated from data published for patients with oLp (100 patients with 302 implants). Data of 27 patients (152 implants) with EB revealed wmSR of 98.7 % following mfp of 32.6 months. For 71 patients (272 implants) with SjS, wmSR was 94.2 % following a mfp of 45.2 months, and for 6 patients (44 implants) with sSc, wmSR was 97.7 % after mfp of 37.5 months. One case report on one patient each with Pe (two implants) as well as sLE (6 implants) showed 100 % SR following at least 24 months. Guidelines regarding implant treatment of patients with oLp, Pe, EB, SjS, sLE or sSc do not exist nor are contraindicating conditions defined. Implant survival rates of patients affected are comparable to those of healthy patients. For implant-prosthetic rehabilitation of patients with Pe and sLE no conclusions can be drawn due to lack of sufficient clinical data. Implant-prosthetic treatment guidelines regarding healthy patients should be strictly followed, but frequent recall is recommended in patients affected with oLp, SjS, EB, SSc, Pe or sLE

Biotechnological advances in neuro-electro-stimulation for the treatment of hyposalivation and xerostomia

Treatment of xerostomia is a common clinical challenge in the oral medicine practice. Although some treatments have been used to improve the symptoms of xerostomia, none is completely satisfactory for the patients who suffer of this alteration. In the last years non-pharmacological treatments based on electro-stimulation for the treatment of xerostomia have been developed. This review is aimed at presenting new developments for the treatment of xerostomia, applying neuro-electro-stimulation by miniaturized intra-oral electro-stimulators. These devices increase salivary secretion and improve symptoms of oral dryness. Their effect is obtained by means of stimulation of the lingual nerve, in whose proximity the electrodes of the apparatus are placed. The objective of this mechanism is both to directly stimulate the salivary glands controlled by that nerve and to enhance the salivary reflex. Clinical studies have been carried out that have demonstrated the wetting effect of the method described in this article

Electrostimulation of the lingual nerve by an intraoral device may lead to salivary gland regeneration : a case series study

Salivary gland function is controlled by the salivary reflex, whose efferent arm is composed by the parasympathetic and the sympathetic divisions of the autonomic nervous system. Parenchymal injury is the main salivary gland involvement of Sjögren?s syndrome and head and neck radiotherapy, but neural damage has been reported as well. Recently an intraoral device for electrostimulation of the lingual nerve in vicinity to the lower third molar has been introduced. At this point this nerve carries efferent fibers for the innervation of the submandibular, sublingual and several minor salivary glands and afferent fibers of the salivary reflex. Therefore, excitation of these fibers potentially leads to increased secretion of all salivary glands. Thus, the study objective was to assess whether comprehensive neural activation by electrostimulation of the lingual nerve carries the potential to induce the regeneration of damaged salivary glands. The device was tested on three patients with no collectable resting and stimulated secretion of saliva during a double blind, sham controlled period of two months and nine open-label months. All three subjects developed the capacity to spit saliva, not only in direct response to the electrostimulation but also after free intervals without electrostimulation. In addition, their symptoms of dry mouth severity and frequency improved. This recovery is probably due to the combined effect of increase in secretory functional gland mass and regain of nervous control of the secretory elements and blood vessels. Both are phenomena that would contribute to gland regeneration
